or was that "just" ambition?

LonelyGM no I never made it to actual GM I was on the edge of becoming an IM when I was 14 and lost a very improtant game against a spanish guy in an international competition in Valencia 10:22
and so I gave up for a year and since then I regret that decision because I couldn't get back 10:23
10:23 vendethiel left
LonelyGM my actual rating dropped heavily since then... I'm like 1900-2000 ELO currently... and my dream is to design a chess engine that would play exaclty like Bobby Fischer did once :) dreams haha 10:24
moritz well, I have an ELO (or the German equivalent). It's 0 :-)
I played one rated game, and lost it 10:25
10:25 pecastro left, zakharyas left
LonelyGM moritz: everony starts at 900 ELO and you rating is not "real" until you play a draw 10:26
btw I think chess is very similar to what you guys are doing with perl6 I try to implement this into my chess strategy :) 10:27
masak interesting.
how is it similar_
?
moritz a game is mostly searching and scoring, a compiler is translating/transforming
moritz doesn't see the similarity yet 10:28
LonelyGM well, chess is just partly about discovering patterns and applying your strategy for that
moritz ah, so you're saying it's similar to programming as a whole 10:29
I think I can agree with that
10:30 vendethiel joined
LonelyGM the essence of chess is basically to figure out what the opponent wants, you are language designers first and then coders, Larry told me that he might not be the best coder in the world he is good in finding out what other people wants and giving them the opportunity to do that 10:30
dalek kudo/nom: b9e7dbc | lizmat++ | docs/ChangeLog:
Mention native arrays
LonelyGM in chess you have to figure out what the other wants and not to give them the opportunity
10:31 pecastro joined
LonelyGM and of course when you are thinking of an attack and series of moves you are thinking in algorithms 10:31
when you have a shady area after a move that could be a parameter which could change the further outcome of the algorithm
if you could actually know how the compiler reacts to each and every code you wouldnt have to write the code bc you would no that it is faulty 10:32
in chess you do these experiments in your head and hope that you are precise enough to succeed :)

i have this super-ugly construct which seems to not work 19:43

my sb4 $value_sz = $valuebuf.bytes;
my @valuep := CArray[int8].new;
@valuep[$_] = $valuebuf.[$_]
for ^$value_sz;
vendethiel FROGGS: ha :(
FROGGS abraxxa: just pass that buf 19:44
abraxxa: passing a VMArray (what a buf is underneath) is implemented since 2015.02 19:46
abraxxa so i have to define the parameter differently?
currently i've defined it as CArray[int8] $valuep,
retupmoca abraxxa: sub c_function(Buf) is native { ... }; my $buf = $v.Str.encode('utf8'); c_function($buf); 19:47
abraxxa that would become OraText $valuep is encoded('utf8'),
FROGGS you can also put utf8 instead of Buf in the signature 19:48
because:
m: say "foo".encode('utf8') ~~ utf8
camelia rakudo-moar b9d6d3: OUTPUT«True␤»
FROGGS m: say "foo".encode('utf8') ~~ Buf

19:51 terahzer joined
FROGGS abraxxa: is that good? 19:52
I mean, do you make progress?
abraxxa i thought the bind causes the segfault but it seems the sql statement execution afterwards does
i have to look into that pointer passing change so i can remove my ugly workarounds
so if I pass a Buf that is an array of bytes internally and NativeCall passes it correctly 19:53

abraxxa i'm doing a similar thing for those: my @indp := CArray[sb2].new; @indp[0] = -1;
void *indp,
Pointer to an indicator variable or array. For all data types except SQLT_NTY, this is a pointer to sb2 or an array of sb2.
FROGGS nowadays: sub foo(int16 $thing is rw) ... { * }
ahh 20:01
then: sub foo(Pointer) ... { * }; my Pointer $a .= new; foo($a); say nativecast(int16, $a)
and you do the nativecast conditionally 20:02
terahzer I am reading the docu,entation of perl 6 on wikibooks; do you think it is usefull for somebody approaching the language to read the Apocalypses, Exeseges and Synopses?
abraxxa i've defined it as CArray[sb2]
retupmoca nine_: you may want 'Blob' in your p5_buf_to_sv signature, since blob8 ~~ Buf is false 20:03
FROGGS well, define it as Pointer instead, and then do the cast... I believe that should work
and if you want to have an int16*, you'd do Pointer[int16] 20:04
20:04 cognominal joined
FROGGS hmmmm 20:04
abraxxa constant sb2 = int16;
i don't need array support for now
FROGGS but then I dunno how to set the value it points to...
abraxxa not sure if I ever will
FROGGS ahh, we need to support malloc directly to be able to pass Pointer[int16] to a C function 20:06
abraxxa: no, what I try describe will help soon 20:07
abraxxa FROGGS: is there already something better than CArray[Type] to specify a pointer to something?
FROGGS abraxxa: that is what I talk about the last ten lines of mine 20:08
abraxxa is Pointer new?
FROGGS typed pointers are new 20:09
nine_ terahzer: probably doc.perl6.org is a better entry point
abraxxa so i can replace CArray with Pointer, great

FROGGS then you want 'returns Pointer[ub4]', and then you can do: say $ptr.deref
nine_ FROGGS: can you assign to $ptr.deref?
FROGGS nine_: no
abraxxa all the OCI functions return sword s but also lots of return by pointer
FROGGS nine_: we need to implement .malloc or so for doing something similar 20:21
'Cannot unbox a type object comes from' usually means that you forgot to call .new
nine_ FROGGS: darn...that would have allowed me to get rid of nativecast(CArray[OpaquePointer], $err)[0] = self.p6_to_p5($_);
FROGGS err, 'Cannot unbox a type object'

[Coke] (approaching the language) synopses maybe. Everything else is a historical document and will probably confuse.

jnthn [Coke]: In...the MoarVM release?
FROGGS signing it? 20:42

abraxxa how do i change if $v ~~ Int { to also match Rat? 20:46
FROGGS match against Numeric?
colomon Real would be more appropriate. But that’s more than just Int and Rat 20:47
Ulti if $v ~~ Int|Rat {} assuming you really do want to do what you're asking :3 20:48

terahzer what is the sintax for array literals in perl6 when in perl5 would be (0) x 10 for instance? 20:53
20:54 abraxxa left
rurban Got a design question. Do you have the is hidden_from_backtrace trait already implemented? In perl5 context it would make much more sense to support both variants positive and negative. Some XSUBs need a flag to be added to backtraces, like Carp and XSLoader::load and some other functions need it negative to be hidden from backtraces. So implement it as :backtrace for xsubpp and the :-backtrace sub attribute which closely res 20:54
so maybe you want to support a negative trait, like "is !backtrace" 20:55
FROGGS m: sub foo is hidden_from_backtrace { } 20:56
camelia ( no output )
FROGGS is implemented, aye
rurban and negative in some form as perl5 :-attr?
FROGGS rurban: !backtrace look almost like a private method
[Coke] m: sub foo is notimplemented {}

[Coke] (making sure you didn't cheat. ;) 20:57
20:57 pullphinger left
FROGGS rurban: the native form '!backtrace' would only make sense if we had a positive form I guess 20:57
[Coke] m: sub foo is hidden_from_backtrace { die "eek" } ;sub bar() { foo } ; bar
camelia rakudo-moar b9d6d3: OUTPUT«eek␤ in sub bar at /tmp/pImUxDwHYa:1␤ in block <unit> at /tmp/pImUxDwHYa:1␤␤»
terahzer How would you do to do @list = (0) x 5; in perl 6 ?
FROGGS terahzer: operator xx
m: say 1 xx 5
camelia rakudo-moar b9d6d3: OUTPUT«1 1 1 1 1␤» 20:58

terahzer cool
FROGGS rurban: there is no negation form of traits
rurban: because you apply a trait... you can't un-apply it
rurban: like you cannot uncall a subroutine
a trait is a very generic thing
terahzer m: @l = (1,2,3,4); @l »+=« 1 xx 4; say @l;
camelia rakudo-moar b9d6d3: OUTPUT«5===SORRY!5=== Error while compiling /tmp/swMn8Wo3_C␤Variable '@l' is not declared␤at /tmp/swMn8Wo3_C:1␤------> 3@l7⏏5 = (1,2,3,4); @l »+=« 1 xx 4; say @l;␤ expecting any of:␤ postfix␤»
rurban yes, I thought just for shorter names 20:59
FROGGS it is not just a hash like annotation
terahzer m: my @l = (1,2,3,4); @l »+=« 1 xx 4; say @l;
camelia rakudo-moar b9d6d3: OUTPUT«2 3 4 5␤»
terahzer this thing »+=« is difficult to type on most keyboard, how do you do that ?
FROGGS rurban: like the 'is inline("C")' trait wraps a routine and compiles+runs C code...
you cannot un-apply that 21:00
rurban Do you have subs which do not record their calling context, like perl5 xsubs?
FROGGS rurban: not that I know offhand
rurban ok. So I will have a minor perl6 deviation on this one
It's just syntax, the concept is the same 21:01
sub inner is hidden-from-backtrace { die "OH NOEZ" }; 21:03
looked pretty lispy and unperly to me :)
skids terahzer: First you make sure you have a compose key mapped. Then compose > > .
vendethiel skids: EIMONWINDOWS 21:04

[Coke] on mac it's alt-\ and alt-| to get «» 21:07
Ulti lol who is @KruthikDhillon on Twitter? they appear to only tweet trollish comments about #perl6 and weird gushing messages about "Elavan" 21:08
exclusively just those two topics x___X
[Coke] your code editor may also have a way to insert them, even if your OS is unhelpful. but most OSes have some way for you to generate non-ascii.
terahzer the original idea was to allowing @l = (1,2,3,4); @l >>+=<< 1 ; say @l; (list scalar operation) what was ambiguous about that? 21:09
jnthn terahzer: You get that with >>+=>> 21:10
terahzer Good, why was it deemed necessary to discriminate?
jnthn Point the things outwards to get DWIM-y behavior.
FROGGS discriminate? 21:12
jnthn I think that was decided before I was around here. At a guess, so you have a way to indicate you expect the same size so you don't get caught out by the auto-extending behavior.
FROGGS ahh
terahzer by the way direction of arrows is intuitive 21:13
jnthn It may be that the one form optimizes (e.g. to SIMD stuff) easier.
terahzer let you do things like @l = 2 <<+<< @l
jnthn Though we ain't do that just yet :)

terahzer more than SIMD on hyperoperators, I think that multithreads in the map function could be an huge performance boost

hoelzro I did a fair amount of work last night to remove linenoise/readline from MoarVM, and I broke out the functionality into a Linenoise module 21:52
japhb hoelzro++ 21:53
hoelzro we could direct users to install Linenoise via panda, or we could bundle Linenoise with rakudo; what would be the preferred approach?
FROGGS I guess we want to continue shipping a REPL 21:54
japhb Though, does that mean that nqp no longer has a REPL?
We definitely want a REPL for Rakudo.
hoelzro there's still a REPL
japhb (Standard, I mean.)
hoelzro it just uses Linenoise.pm rather than nqp::readlineint_fh for reading lines 21:55
falling back to nqp::readline if the former isn't available
the cool thing is that the REPL in my fork now has tab completion
japhb Oooh
hoelzro which I think would have been too hard to do with readline at the VM level 21:56
(well, we would've needed a nqp::readlineint_completion_cb op, which seems like overkill)
FROGGS hoelzro: and the REPL also works for nqp-m?
hoelzro checks
yup
although it doesn't have history like it used to =/ 21:57
so that's a drawback
21:58 diana_olhovik left
lizmat I would think Linenoise.pm would be a nice addition to the core 22:04
hoelzro I'm just not sure if it's core or star worthy' 22:05
jnthn Well, doesn't the REPL depend on it?
Or, or won't the REPL depend on it...
hoelzro it tries to load it; if it can't, it falls back to nqp::readline 22:06
jnthn *nod*
Do we have a Readline.pm that can be tried also? :)
hoelzro jnthn: I would like to have the REPL do that too
jnthn *nod*

I'm not confident enough in my Moar/NQP/Rakudo fu to push anything non-trivial to nom|master 22:08

jnthn Well, also we don't want to land such a thing this side of the relese :) 22:09
*release
hoelzro >:) 22:10
I wouldn't expect that; it was (I think smls?) comment that inspired me
if it's in 2015.04, that's cool
the completion work is sitting uncommitted at home; it will need a fair amount of work
also, p6-linenoise doesn't bundle linenoise.so, and I needed to use a patched version of linenoise to re-enable blocking on STDIN 22:11
